Mobile Communication Terminal

FIG. 1 is a diagram illustrating an external appearance of the mobilecommunication terminal according to an embodiment of the presentinvention.

Referring to FIG. 1 , the mobile communication terminal 100 according tothis embodiment can include a display unit 110 and an activation button120. The mobile communication terminal 100 can further include a camera130.

Although the display unit 110 is provided on the front side of a frameconstituting the mobile communication terminal 100, the activationbutton 120 is provided on a lower part of the display unit 110, and thecamera 130 is provided on an upper part of the display unit 110 asillustrated in FIG. 1 , other forms may be configured. For example, thedisplay unit 110 need not necessarily be formed on the entire surface ofthe mobile communication terminal 100. That is, the display unit 110 isonly required to be formed on at least part of the mobile communicationterminal 100, and the activation button 120 is only required to beformed on a part different from that of the display unit 110. Inaddition, the camera 130 can be formed on the other side on which thedisplay unit 110 is not provided in the mobile communication terminal100.

The display unit 110 displays various information regarding operationstates of the mobile communication terminal 100, and also displays aninterface for a user's input if the mobile communication terminal 100drives a touch screen. In general, if a state in which the user'soperation on the mobile communication terminal 100 is absent continuesfor a predetermined period of time, the mobile communication terminal100 is in the inactive state. The user's operation refers to an inputthrough the interface displayed on the display unit 110, an operationthrough the button 120, or an operation through a function key (forexample, a volume control key or the like). A condition in which theinactive state is reached can be set by the user. For example, thecondition can be set using a setting menu through the interfacedisplayed on the display unit 110. On the other hand, the state can beswitched to the inactive state by pressing another button (for example,an ON/OFF button) provided on the mobile communication terminal 100. Forexample, the mobile communication terminal 100 can be completely turnedoff if the ON/OFF button is pressed for a long time when the mobilecommunication terminal 100 is in the active state, but the mobilecommunication terminal 100 can be in the inactive state as acommunicable state in which a phone call can be received if the ON/OFFbutton is pressed for a short time.

The activation button 120 is means for switching the mobilecommunication terminal 100 from the inactive state to the active state.That is, if the user presses the activation button 120 when the mobilecommunication terminal 100 is in the inactive state, switching to theactive state is performed. FIG. 1 illustrates a state in which a lockscreen is displayed on the display unit 110 after pressing theactivation button 120 when the mobile communication terminal 100 is inthe inactive state. However, the activation button 120 can function asmeans for another operation (for example, means for moving to a standbyscreen while a certain operation state is displayed on the display unit110 or means for displaying a list of programs currently beingoperated).

According to an embodiment of the present invention, if the user pressesthe activation button 120 when the mobile communication terminal 100 isin the inactive state, the mobile communication terminal 100 performs apredetermined operation in addition to switching to the active state.For example, image information is displayed on a lock screen of thedisplay unit 110 when the predetermined operation is being performed.The image information is displayed on a lock screen of the display unitwhen the predetermined operation is being performed. The lock screen isconfigured to be displayed when the mobile communication terminal 100changes from the inactive state to the active state. The display unit110 can provide an unlock means on a part of the display unit 110 whenthe predetermined operation is being performed.

When the mobile communication terminal 100 is in the inactive state, theuser can set an operation to be performed by pressing the activationbutton 120. For example, an operation of the mobile communicationterminal 100 connected to the activation button 120 can be set using asetting menu through the interface displayed on the display unit 110. Inaddition, according to an embodiment of the present invention, anoperation which differs according to the number of presses or a presstime of the activation button 120 can be performed when the mobilecommunication terminal 100 is in the inactive state. For example, afirst operation can be set to be performed if the activation button 120is pressed once, and a second operation can be set to be performed ifthe activation button 120 is continuously pressed three times. Inaddition, as another example, the first operation can be set to beperformed if the activation button 120 is pressed once for a short time,and the second operation can be set to be performed if the activationbutton 120 is pressed once for a long time. The mobile communicationterminal 120 can include a predetermined clock circuit or timer tocalculate the cumulative number of continuous presses of the activationbutton 120 and measure a period of time for which the activation button120 is pressed. For example, the number of presses is determined to betwo if the activation button 120 is re-pressed within a threshold timeafter one press. If the activation button 120 is pressed for thethreshold time or more, a long press of the activation button 120 can bedetermined. Operations capable of being performed by pressing theactivation button 120 in the inactive state will be described later.

According to an embodiment of the present invention, a sub-display unit121 can be provided on the activation button 120. Information regardingan operation to be performed by pressing the activation button 120 canbe displayed on the sub-display unit 121. Various types such as a shape,a character, a graphic, and color can be displayed. When the displaytype is the shape, a circle, a triangle, a rectangle, a hexagon, or thelike can be displayed. For example, the circle can be displayed on thesub-display unit 121 when the first operation is set to be performed bypressing the activation button 120, and the triangle can be displayed onthe sub-display unit 121 when the second operation is set to beperformed by pressing the activation button 120, and vice versa. Adisplay type of the sub-display unit 121 and a correspondencerelationship between operations and displays can also be set by theuser. For example, the user can select the first operation as theoperation to be performed by pressing the activation button 120 from asetting menu and select the triangle as the display type of thesub-display unit 121 of the activation button 120. Accordingly, the usercan recognize that the first operation is performed when the user haspressed the activation button 120 because the triangle is displayed onthe sub-display unit 121 even when the mobile communication terminal 100is in the inactive state.

Although the sub-display unit 121 can be implemented by a generaldisplay such as liquid crystal, a liquid crystal display (LCD), or alight emitting diode (LED), the present invention is not limitedthereto.

An operation of controlling driving of the display unit 110 and thesub-display unit 121 can be performed in the same processor and the samemethod or in different processors and different methods.

Hereinafter, various embodiments for operations of the mobilecommunication terminal 100 capable of being performed by pressing theactivation button 120 will be described.

The camera activation element 321 activates the camera 130 provided inthe mobile communication terminal 100. According to the activation ofthe camera 130, a video currently captured by the camera 130 isdisplayed on the display unit 110. If an eye or face of the user isimaged by the camera 130, the eyeball detection element 322 performs afunction of recognizing and extracting an eyeball of the user. A generaleyeball detection algorithm can be used for eyeball detection. Thehealth information acquisition element 323 acquires various healthinformation through the eyeball detected through the eyeball detectionelement 322. It is possible to recognize a stress index, a diabetesindex, or retinal diseases of the user through a color or health stateof the eyeball. A well-known algorithm in the related art can be used asan algorithm for detecting health information from characteristics ofthe detected eyeball.

The health information acquired as described above can be transmitted bythe health information transmission unit 330 to the mobile communicationterminal of a protector, a medical authority such as a doctor or thelike, or a predetermined server. Information regarding the protector(for example, a phone number or an e-mail address) can be stored inadvance. The acquired health information can be displayed on the displayunit 110 so that the user can check the acquired health information.

The above-described operations, that is, the eyeball detection functionand the health sensing function based on information regarding thedetected eyeball, can be performed by installing a predeterminedapplication. That is, the application includes an eyeball detectionalgorithm and a health sensing algorithm, so that the operations asdescribed above can be performed by installing the application in themobile communication terminal 100. The user can download thisapplication and install the downloaded application in the mobilecommunication terminal 100. In addition, although an example of onlyhealth sensing through eyeball detection has been described above, it ispossible to install an application, for example, for health sensingthrough face detection, and connect the application to the activationbutton 120. The user can use the functions as described above by settingthe application to be operated immediately when the activation button120 is pressed through the setting menu in the inactive state of themobile communication terminal 100.

When the mobile communication terminal 100 is in the inactive state, theactivation sensing unit 410 senses whether or not the user has pressedthe activation button 120.

If the activation sensing unit 410 senses that the activation button 120has been pressed, the user identification unit 420 operates the useridentification function in various methods.

FIG. 4B is a block diagram illustrating an example of the useridentification unit 420. Referring to FIG. 4B, the user identificationunit 420 can include a camera activation element 421, an iris detectionelement 422, and a user identification element 423.

The camera activation element 421 activates the camera 130 provided inthe mobile communication terminal 100. According to the activation ofthe camera 130, a video currently captured by the camera 130 isdisplayed on the display unit 110. If an eye or face of the user isimaged by the camera 130, the iris detection element 422 performs afunction of recognizing and extracting an iris from an eyeball of theuser. A general iris detection algorithm can be used for irisrecognition. The user identification element 423 performs a function ofcomparing the iris detected by the iris detection element 422 topre-stored iris information of the user, and authenticating the currentuser as a true user if the two match. For this, the user identificationelement 423 can use iris information of the user pre-stored in adatabase. The iris information of the user can be stored by registeringinformation regarding the iris detected by the iris detection element422 using a video of the true user first captured by the camera 130.Predetermined identification information (for example, an identifier(ID), a password, a social security number, or the like) should be inputto change the registered iris information of the true user. If the useridentification element 423 authenticates the current user as the trueuser, the lock state of the mobile communication terminal 100 isreleased and all functions are available. If the current user is notauthenticated as the true user, the lock state continues along with adisplay of an alarm message.

The above-described operations, that is, the iris detection function,the user identification function, and the user authentication function,can be performed by installing a predetermined application. That is, theapplication includes the iris detection algorithm and the authenticationalgorithm based on an iris comparison, so that the operations asdescribed above can be performed by installing the application in themobile communication terminal 100. The user can download thisapplication and install the downloaded application in the mobilecommunication terminal 100. The user can use the functions as describedabove by setting the application to be operated immediately when theactivation button 120 is pressed through the setting menu in theinactive state of the mobile communication terminal 100.

Accordingly, it is possible to efficiently reduce security risks bysetting the user authentication process to be performed through aseparate setting, that is, by pressing the activation button 120, whenthe mobile communication terminal 100 is used in a region vulnerable tothe security risks.

Although an example of an authentication method through iris recognitionhas been described above, other authentication methods, for example, anauthentication key matching method, a password matching method, a facerecognition method, a fingerprint recognition method, and the like, canbe used. That is, one or more authentication methods can be performed bypressing the activation button 120.

4. Location Information Transmission Function
